Books: George R. R. Martin rocks, but is slow as hell in actually
publishing. Douglas Adams, Bernard Cornwell, and J. R. R. Tolkien
(I'm noticing a trend of authors with double "R" initials...)
Robert Jordan: WoT before it started to suck. Neil Gaiman, Isaac
Asimov, and select Piers Anthony... Yeah, those are authors and not
actual books; deal with it.
Movies: Serenity, Gattaca, The Princess Bride, the original Star
Wars, The Boondock Saints, Dead Poets Society, Stand By Me, Kingdom
of Heaven (despite Orlando Bloom)
T.V.: Babylon 5, Supernatural, Doctor Who, Leverage, Burn Notice,
Star Trek: TNG (and DS9, Enterprise and TOS in small doses - but
NOT Voyager), Bones, Battlestar Galactica, The Sarah Connor
Chronicles, House, NCIS
Food: Kimchi, sushi, and steak.
